Also investigate renaming some query files to better clarify their purpose.
Ex: rename queries_common.yml to queries_global.yml

For package target installation of files, look at having version specific query files strip the pg version off of them since they're already going into a version specific folder.
Ex: queries_pg12.yml -> queries_pg.yml
Ex: setup_pg12.yml -> setup.yml
Ex: pg_stat_statements_pg12.yml -> pg_stat_statements.yml
